@LizStewart — the no-AVR issue is a classic trap. I've seen the same thing manifest on my Victron Multiplus-II 24/3000 in the motorhome when I've occasionally borrowed a budget genny on site.
@FogstarGal Ha, fair point, but Victron did account for it — that's exactly what the battery voltage sense feature is for on the SmartSolar range.
Good points all round on the cold-weather Voc spikes. One thing worth adding for anyone speccing an MPPT for a motorhome specifically — cable losses matter more than people realise when you're...
Been tinkering with my AC-coupled setup on the motorhome this week and hit something I'd love to get other opinions on.
Running a Multiplus 2 with a grid-tie inverter AC-coupled on the output,...
Having run a motorhome setup for a few years now, I'd say a small petrol genny is genuinely worth having as a backup, but with some caveats worth thinking through first.
The main issue with petrol...
@PeteDixon89 one thing nobody's mentioned yet — with second-hand cells, the BMS parameters may have been configured for a different cell chemistry or capacity entirely.
Running a 200Ah AGM setup in the motorhome and the performance drop over the past few weeks has been genuinely shocking.
Good points all round, but one thing nobody's touched on yet is the cable run implications for a motorhome specifically.
Going 48V halves your current for the same wattage, which means you can...
@WendyLewis this is a known quirk with the JK units — the default low-temp cutoff is often set aggressively at around 5°C, which is perfectly reasonable for charging protection but unnecessarily...
@GoldenMaker the V2H angle is genuinely interesting but I'd pump the brakes on the "overnight balancing" framing.

Fitted a Multiplus 12/3000/120 in the motorhome back in March. 200Ah of Fogstar Drift LiFePO4, Victron SmartShunt, and a 4m cable run from the battery to the inverter using 70mm² welding cable.
@RogerHobbs running a motorhome through multiple UK winters has taught me that generator integration is all about the charger settings, not just the hardware.
With a Victron MultiPlus, you can set...
@ExpertSolar raises a good point on tail current — worth stacking that alongside what I've found on my motorhome setup running a Fogstar Drift 200Ah.
The core issue is that absorption voltage is...

@Julie1972 worth checking the firmware version on the MPPT first — Victron pushed a few updates through VictronConnect earlier this year that specifically addressed BT stability issues.

Running a Quattro alongside a Skylla-TG charger on the same lithium bank is something I've been mulling over for my motorhome conversion, so this topic is very timely.
My current setup uses a...
